Introduction
============

Implementation of [XEP-0136: Message
Archiving](http://xmpp.org/extensions/xep-0136.html) for
[mod\_mam](mod_mam.md).

Details
=======

See [mod\_mam](mod_mam.md) for details.

Usage
=====

First configure mod\_mam as specified in it's [wiki](mod_mam.md). Make
sure it uses sql2 storage backend.

Then add "mam\_archive" to your modules\_enabled list:

        modules_enabled = {
            -- ...
            "mam_archive",
            -- ...
        }

Configuration
=============

Because of the fact that
[XEP-0136](http://xmpp.org/extensions/xep-0136.html) defines a
'conversation' concept not present in
[XEP-0313](http://xmpp.org/extensions/xep-0313.html), we have to assume
some periods of chat history as 'conversations'.

Conversation interval defaults to one day, to provide for a convenient
usage.

    archive_conversation_interval = 86400; -- defined in seconds. One day by default

That is the only reason SQL database is required as well.
